Sr.no	Column I	Sr.no	Column II
A.	TCA cycle	(i)	Inner mitochondrial membrane
B.	$F_0-F_1$ particles	(ii)	Hans Krebs
C.	End product of glycolysis	(iii)	Oxidative decarboxylation
D.	Pyruvate dehydrogenase	(iv)	Pyruvic acid

• A. A-(ii),B-(i),C-(iv),D-(iii)
• B. A-(i),B-(ii),C-(iv),D-(iii)
• C. A-(ii),B-(iii),C-(iv),D-(i)
• D. A-(iii),B-(ii),C-(i),D-(iv)

Answer 1

The correct option is A A-(ii),B-(i),C-(iv),D-(iii)

A. TCA cycle or Krebs cycle: This cycle is been named after the German biochemist in England Sir Hans Krebs who discovered it in 1937. It takes place in the mitochondrial matrix.

B. F${}_0$- F${}_1$ particles: Oxidate phosphorylation in mitochondria is catalysed by a multicomponent enzymatic complex called ATPase or coupling factor. It has a stalk (CF${}_0$) and a headpiece(CF${}_1$) located completely across the inner mitochondrial membrane.

C. Glycolysis: The net yield of the process is @ ATP molecules and 2 NADH molecules +2H${}^{+}$ for each glucose molecule oxidized to pyruvic acid.

D. Pyruvate dehydrogenase: The pyruvic acid during glycolysis enters in the mitochondrial matrix, undergoes oxidative decarboxylation and forms acetate in the presence of enzyme pyruvate dehydrogenase.

So, the correct answer is 'A-(ii), B-(i), C-(iv), D-(iii)'.
